Doing power bank does not charge. What to do if the Power bank does not fully charge the battery of your smartphone or tablet. % stands still not added

According to feedback from service center employees, charging problems are one of the most common reasons for contacting them. Sometimes this is due to really serious problems, for example, the failure of the power controller, which requires replacement of components. But more often than not, problems with charging the device can be solved by yourself. Here is a list of steps, in order of increasing difficulty, that you can do yourself before contacting a repair shop.

1. Remove debris, dust and grains of sand

If you do not part with your smartphone for a minute, carry it in your jeans pocket and drag it to the sea, then sooner or later so much garbage will accumulate in the charging socket of the gadget that it will completely refuse to charge. Therefore, the first step is to visually inspect the USB port. Then blow it out with a can of compressed air and brush gently with the bristles of a hard toothbrush.

2. Clean the contacts of the USB port from oxidation

Sometimes the device does not charge due to oxidation of the contacts. This happens especially often if the smartphone has not been used for a long time or is operated in unfavorable climatic conditions. In this case, cleaning the contacts with a toothbrush soaked in alcohol, or even a fine needle, can help you out. Do not forget to first turn off the smartphone and remove the battery from it, and perform the operation itself as carefully as possible.

3. Replace the cable

The next weak link to check is the USB cable. Their lives are often full of trials and hardships, so it is not surprising that some of them may die without any warning. The easiest way to check for this malfunction is to take a known working cable from another device and connect it to your gadget. If the problem persists, then go to the next item.

4. Test the power adapter

The charger is also a frequent source of problems. We are talking about that very small box that plugs into an outlet. First, touch it to check the temperature. An adapter that is too hot or too cold can be an indirect sign of a breakdown. Make sure the cable connection socket is intact and clean it if necessary. Try to find another power adapter that matches your specifications.

5. Buy a new battery

Modern technology has made batteries much more durable than before, but still not forever. Each battery has its own lifespan, expressed in the maximum number of charge and discharge cycles. If you use your gadget heavily and it has been for several years now, then it is likely that the battery life is running out. To test this, just take it out and make sure it has no thickenings, smudges, or other signs of aging. However, it is most reliable to check the voltage outputted by the battery with. If it is too low, then you should look for a replacement for it in a service center or online stores.

6. Do a factory reset

If you went through all the points and none of them helped you to find out the cause of the problem, then perhaps the whole point is a software failure. The Android operating system collects device usage statistics in order to prevent the battery from draining completely. In some devices, a full discharge will cause the built-in power controller to malfunction, which in turn prevents the device from taking charge as usual. In this case, a factory reset can help (remember to back up important data first). Of course, this is a last resort and should only be resorted to if you have tried everything else.

In this article, I tried to describe the most common problems with charging gadgets and ways to solve them. Of course, in real life there can be many more of them. Write about the cases that you encountered in the comments.

Phone or tablet not charging? We have a few tips and tricks in store for this case.

During the entire stay with its owner, the smartphone can throw out different numbers, but one of the most common problems is related to the fact that it suddenly refuses to charge. And there are many reasons for this behavior, some of which we highlight in this article. As well as tips to try before you go to the service center and pay money for repairs.

Accessory issues that prevent your phone from charging

When identifying a problem, the first step is to check the most likely causes of the problem. A few tips below are pretty simple, done quickly and without any additional tools.

Inspect the charger cable

The charger cable is usually the cheapest and fragile part. It can become unusable if twisted or bent too much. Therefore, it is worth trying to use a different cable that is definitely not damaged.

For example, borrow from a friend or work colleague if there is no spare at home.

And then you just need to connect this cable to the charger, then to the phone and see if it's charging or not. If not, then the problem is not with the cable, but with something else.

Check power supply

Likewise, it will not be superfluous to check the charger. Again, for testing, we use another, one hundred percent working power supply and look at the result.

If a cable or charger is found to be a problem, inexpensive new options can always be purchased, including online.

Perhaps it is because of the case that is too large

Those who recently bought a protective case for their smartphone need to make sure the cable fits snugly into the connector.

Sometimes the large case will cause the charging cable to move so much that the connection is broken and charging stops. It rarely happens that the problem is in the case, but it doesn't hurt to check this option.

Common Android problems preventing charging

So, we checked: it's not the cable, not the charger or case. Then let's check the device itself.

If the smartphone does not charge after a long period of inactivity with an empty battery, it may need a little “shake”. You should try several times to quickly insert and remove the charger plug from the outlet. Sometimes it helps.

You can also look at the manufacturer's website or the support forum, perhaps there you will be able to find some working option or a combination of actions to solve this problem.

Clean the contacts in the connector

Over time, the connector on the phone becomes clogged with small debris, dust and dirt. A high concentration of these unwanted guests can lead to charging problems. To clean the contacts, you just need to blow well into the connector.

If the dirt does not want to leave the cozy socket of the smartphone just like that, you can clean the connector with a vacuum cleaner or an unbent paper clip, the main thing is to do it very carefully in both cases. For safe vacuum cleaning, turn off your device and use a plastic funnel to avoid accidentally scratching your phone.

You can also use a rolled up piece of paper with a sharp angle that you can tuck into the slot to clean up the mess.

Update software

Not often, but sometimes due to operating system updates, there are charging problems or errors in battery power management.

If the OS on the smartphone is very recent, and about the same time there was a problem with charging, maybe these events are related.

In this case, you may need to rollback to the previous version of the operating system, the problem is that not on every device this is possible.

But instead, it's better to check if another smartphone update has been released. Usually, new software fixes problems in the past.

1. To update the system on Android, open the "Settings", go to the "Software Update" section and select the "Update" item.
2. For iPhone users, a slightly different path awaits: Settings → General → Software Update.

Change battery

This is not possible on most modern phones, since the battery is built into the case. But if the phone or tablet has a removable battery, then it is worth replacing it with a new one.

Batteries naturally degrade over time and cannot store as much electricity as they could before. This usually happens for a long time, but in some cases it can fall like snow on your head. In order not to spend money on buying a new one, it would be wiser to take a suitable working battery from friends or acquaintances.

You can also go to the store, explain the situation and ask for a battery to check.

Is it time to buy a new phone?

For those who do not want to bother with finding the cause of the problem at all, there are only two options. Either carry the gadget to a service center (if the warranty is still valid, we carry it to the seller from whom we bought it), or replace the smartphone with a new one.

Obviously, the last option is the most expensive, but if the device has worked for a long time and has recently begun to malfunction, then why not replace your old man with a younger device?

After reading our article, even those who are not particularly friendly with technology will be able to figure out a little what's what. Simple, but miraculous recommendations will make the naive - wise, and the defenseless and insecure - experienced experts in the question: "What to do if the phone does not charge?" Most likely, even people who are not technically savvy will be able to adequately answer an oversized "guru" from an independent workshop that the cause of the malfunction lies not in the red button and not even in the fact that the beloved dog likes to play with a hanging charger cord (charger). After all, everything that can be done at home, you will know, and this, believe me, is not enough. Let's drop the lyrics and move from words to practice.

Why the phone won't charge: the main reasons and how to fix them

As a rule, such a malfunction occurs as a result of mechanical or chemical stress. However, one cannot discount the software failure of a mobile device. Even such a modern phenomenon as "electronic malware infection" can cause problems in the power supply system of a smartphone. Nevertheless, correctly performed diagnostics will dot all the i's.

Is your

If your phone stops charging, the power cord should be visually inspected first. You may find clear signs of damage to the outer insulation of the cable. Deformation in the form of kinks and stretching should also not hide from your view. If everything is fine with the wire, and the plug has not oxidized, ask your neighbors, acquaintances or a colleague for help, maybe one of them has exactly the same charge. A positive result - go to the store and buy a new charger, no - we proceed further.

Optional: USB check

As a rule, a mobile device purchased from a store comes with a sync cord (DATA cable). Connect your cellular device to your computer. via USB?

Disconnect everything from your PC. No reaction? It's a bad situation, but it's too early to get upset, there are several more methods with which you can try to restore the "energy life" of a mobile phone.

Software glitch and what the virus is capable of

Often, smartphone owners sin by installing various programs and applications that expand the capabilities of the device. And without even thinking about the "decency" of the developers and not attaching importance to the nuance that the distribution source is filled with extremely dubious content. As a result, the working firmware starts to "glitch". The charge indication may stop working altogether, and when a virus enters, the phone will quickly lose the battery charge that once lasted for two or three days. Note if any of the wireless modules turn on spontaneously. Found a snag - uninstall the program and neutralize the malicious code.

mobile device

Remember: never panic when deciding what to do if your phone won't charge: it can always be fixed.

In bright light (and if you have a magnifying glass, it's wonderful at all), inspect the inside of the nest. “Chic and shine” is a great sign! Contamination and chemical deposits in the form of oxidation require cleaning.

Remember the saying "the further into the forest, the more firewood"? So, do not try hard to poke around with various improvised means of the narrow channel of the contact connector - you can still damage the whole system element. Caution, a thin brush and alcohol are all you need in this case.

A good solution to the question "What to do if the phone does not charge" is a simple experiment. Insert a known good memory device into the connector of the mobile device and, without obvious effort, shake the plug in different directions at a frequency of one second. The indication came to life - you are in the workshop, "dull" - we read the next paragraph.

Accumulator battery

If the energy supply of the battery has completely dried up, it is likely that the autonomous battery has lost its starting impulse. In such a situation, you simply cannot do without a universal memory.

• Install the battery into the holder and, observing the polarity, supply electricity to the "plus" and "minus" contacts.
• In just 5-10 minutes, the battery can be inserted into the phone.

If all is ineffectual and the miracle did not happen, then the next stage of the project "what to do if the phone does not charge" will be a trip to the nearest workshop or service center.

Natural ending

Falling the phone and hitting a hard surface, even when it is shockproof "from birth", does not lead to anything good. As they say, luck is temporary. As a result of this kind of mechanical damage, the owner of a mobile device may face the following problem: the phone is not charging - charging is in progress. Often, due to a strong blow, the cell phone battery breaks down. The visually observable indication is really just software graphics, which, in fact, is wasted. Since the batteries are not refueled. There are two ways out: either repairing the power controller of the cellular device, or replacing the battery. In the first case, you simply cannot do without masters.

Finally

Hopefully, the question of why the phone won't charge is resolved for you today. Nevertheless, I would like to give you a few recommendations as a reward for curiosity:

• Don't use too often
• Do not allow deep discharges of the battery to zero.
• Do not leave the phone in the heat or, conversely, in the cold.
• Install antivirus protection on your phone (if the software allows it).

Have a nice day and successful renovation!

We have already found out a lot about portable Power banks, and now I would like to talk about cases when Power bank does not charge the phone, what to do and what are the ways to solve this problem. Do not think that this trouble can only befall low-quality cheap models. Even the owners of renowned "energy stores" are not insured against device malfunctions.

In fact, many of us do not always correctly diagnose our gadgets. Perhaps the mope is not a power bank, but a mobile device. Therefore, the first thing to do is to put another device (smartphone, tablet or e-book) on "recharge". Or connect the device to a fixed network and see if energy recovery is underway. If charging does not go, then we begin to deal with the power bank. For iphone, the most common reason for poor charging is port contamination, so if you have owned a gadget for a long time, then you should start with cleaning.

The second step in diagnostics is to check the integrity of the USB cable. The presence of cracks and kinks should alert you. Try using a different cable. If the phone is charging safely, then it will be enough just to replace the damaged cable.

Problems with power from an external battery can be of the following plan:

1. at first, the filling of the battery is in progress, but then it is interrupted;
2. charging is very slow;
3. the battery capacity in the phone is not fully replenished;
4. the gadget does not charge at all.

There will be a solution for each specific case. Let's consider them in more detail.

Initially, charging is in progress, but then it is interrupted

If you have a Chinese power bank, then it is quite expected that the declared capacity does not correspond to the real one. In this case, for a device with a real capacity of 3000 mAh, it will be problematic to fully charge a smartphone with a 2200 mAh battery. What to do? Buy a portable battery with twice the capacity of a smartphone.

Another reason that the power bank first charges the device, and then stops, may be hiding in the controller, which interrupts the power supply due to overheating or failure. It is possible that the premature completion of the process is associated with a malfunction of the contacts, which at times simply go away. More specific information can be obtained only after inspection at the service center.

Low charging speed

Often, users are faced with the need to charge the iPhone from the power bank only when it is turned off. The only disadvantage is that everyone would like to stay in touch or continue to "dig" the Internet while recharging, and not patiently wait for several hours. So the whole point of the portable battery is lost. So why does the phone have to be turned off? The problem is hidden in the very low charging speed, which does not cover or barely covers the current consumption rate.

This can be due to:

• • defective controller;
  • insufficient current at the output (if the bank has a 1 A connector, and the smartphone needs 1.5 A, then the energy transfer rate will noticeably drop);
  • too thin a cable that cuts off the current and voltage (ideally, you should not use the universal wires that come with the kit, but the original ones bought in a specialized store);

• simultaneous connection of several devices to a battery with a small capacity.

Running "heavy" applications and viruses on the phone can interfere with full charging. Also, if the power bank does not charge the smartphone well, then it is worthwhile to calibrate the battery. To do this, you must first completely discharge the batteries, and then charge up to 100% and do this 3 times. You need to calibrate both the power bank and the smartphone. If the phone is more than 3 years old, then we must not forget about the natural process of reducing the capacity. Visually inspect the battery for bumps and bulges - you cannot use such a battery.

Smartphone cannot be charged to 100%

We touched on this problem in part in the previous sections.

Regardless of the reason, before visiting the service center, I recommend doing the following:

1. check if a full charge takes place when the smartphone is turned off;
2. calibrate using a fixed network.

It is quite possible that it is not a power bank that does not fully charge the smartphone, but simply that the program incorrectly displays the charge level. To check this, you need to use additional devices, or compare with the process from a 220 V.

The phone does not charge at all

The first thing to pay attention to is the compatibility of the power bank and the smartphone model. If the power is incompatible, the bank accumulates energy, works properly, the indicator blinks, but does not charge, the connected device. To check, connect another smartphone and see if it charges. If it turns out that the power bank does not charge only your smartphone, then there is only one way out - to buy another, having specified in advance about compatibility.

If earlier the transfer of energy went smoothly, but suddenly the power bank stopped charging the phone, then there is definitely a malfunction, or one of the two batteries is worn out. The malfunction can be related to the cable, the condition of the connectors and the board. The reason may be a fall, improper operation, the action of high humidity (oxidation of contacts), a banal depletion of battery life.

The recommendations provided in the article should be taken as advice, not instructions. They will help to understand the problem and avoid unreasonable contact to the service center, but in the event of a serious malfunction, specialists must solve the problem. Incompetent "treatment" of the device can lead to irreparable consequences.

Until next time on my blog. Best regards, Rostislav Kuzmin.

When the phone is connected to a portable battery, the charging process does not work normally and cannot be charged. Or it discharges very quickly. Or the charge lasts a few seconds and stops. What to do if the external battery does not charge the phone - we consider possible options and give answers.

An external battery, a portable charger, a portable battery, a universal battery, "Power Bank" (energy saver, English) - these are all synonyms that denote a device that you can have with you for the purpose of autonomous charging of devices.

To charge your phone normally from an external battery, you must first select it correctly. When buying, of course, the first thing they pay attention to is size and weight. They try on how it fits in the hand (along with the phone), what place it takes in a purse or in a bag.

When choosing a Power Bank, you need to pay attention to the size of the device

But its most important parameter is capacity. It should be remembered that its efficiency is approximately 80 percent of the capacity indicated on the packaging (nominal). The rest is converted into heat during operation or lost during transmission.

Current strength

Also, the case of the universal battery is marked with the current value at the connectors and which is actually supplied for energy storage. On the one hand, the speed of the process depends on this value, and on the other, some devices (or rather, their controllers) require compliance with a clear value.

Typically, a current of one ampere is considered normal for a telephone.

Identifying problems

If you find problems with the transfer of capacity from the portable charger to the phone battery, you first need to make sure that the “Power Bank” -cable pair is working properly.

To do this, we connect another gadget to the device. And if the process goes well in it, it means that the cause of the problem is hidden in the phone itself.

Then you need to move on to diagnosing the problem - how exactly does the phone not charge?

• Not charging at all?
• Is it charging extremely slowly (the current discharge of the mobile is not covered by the incoming charge)?

Port contacts

Poor contacts inside ports due to manufacturing defects or frequent disconnections can cause no electricity flow.

To eliminate such a problem, you need to remove the battery with the phone turned off and gently lift the fasteners inside the port with an object such as a toothpick. After that, return everything to its place.

Replacing a broken wire

Broken wire

Violation of the charging process may also be due to a poor-quality or broken wire. Currently, due to the reduction in cost, wires are made very thin and delicate. During their life cycle, they are constantly twisted, pulled together in different ways several times a day. No wonder their breaking, imperceptible from the outside.

You need to check the operation of the wire using another cable. Replace if necessary.

Cleaning port contacts

Someone has more, someone less, but one way or another, the inner part of the phone gets clogged. Small debris, fabric rolls, dust, as well as "wreckage" stuck inside the ports can cause a power failure inside the phone. Carrying out a sweep will return the smartphone to a working state.

IMPORTANT. Do not charge in a humid or hot environment. If you connect it to the outlet for too long, the contacts will fuse with the plastic and even the batteries will explode. - Defense mechanisms do not always work! And factory defects are no exception.

Damaged phone charging connector

Checking the battery

Despite the number of charge-discharge cycles, the phone battery does not last forever. Usually it will work without problems for two years. But over time, it becomes more and more difficult for her to hold (accumulate) the charge. You need to make sure it works.

If there is deformation or swelling, corrosion, replace the element immediately.

ADVICE. An interesting simple way to check a non-removable element is offered - to try to twist it on a flat table like a whirligig: the problematic one will twist easily.

Is the outlet better?

If you cannot fully charge the battery from an external battery, you should try to charge it from a regular wall outlet. In this case, the volume of supplied electricity can be up to two times higher than when supplied through the USB port.

Try to charge your smartphone from an outlet

"Power Bank" / wire

Another reason for insufficient power supply may be the use of "outside" devices. In this case, the strength or power of the current supplied to the battery may not be enough to accumulate the resource.

Running applications

Services, services, or applications running on the phone can be the culprit for weak charge flow. And this is not surprising - they require a lot of energy resources. This is especially true for toys, skype in audio-video communication mode, hard Internet surfing, using high brightness on the monitor, connecting to 4G networks. The cardinal way to speed up the charge is to turn off all these delights. And the most reliable one is to turn off the phone completely.

Calibration

Sometimes modern devices make unjustified mistakes. For example, the phone switches itself off due to the fact that “it considers” its charge to be less than it actually is - no more than two or three percent. And the corresponding message is sent to the system. Although the gadget is charged.

Calibration is exactly the process of "teaching" the battery its capabilities. Helps solve many nutritional problems before they occur. It is worth doing this before you have to update the batteries with new ones.

You need to calibrate your smartphone

Update-rollback

Application updates, firmware installations, and downgrades can also cause disruption to power flow.

This is explained by the fact that the new devices are optimized for modern versions and are equipped with more powerful batteries. But those purchased even a couple of years ago cannot always cope with the load.

Therefore, if a sharp change in the efficiency of a gadget is detected, it is worth trying to roll back its software. Although it happens that the new version just reduces the exorbitant power consumption.

The presence of current in the outlet

If the above methods do not work, it is worth really checking the presence of voltage in the outlet or in the USB port. As funny as it sounds, this is also possible.

The last option is to replace the portable device.

Viruses

Through various network windows, the phone can be infected with viruses. Some of them, due to excessive activation of an application, can drain the energy supply (for example, the Carib virus seriously activates Bluetooth).

IMPORTANT. You cannot do without a visit to the service center in case of a sharp discharge due to a vibration or sound signal. This occurs when there is a problem with the power amplifier.
